Configuring POP3 Service

POP3 protocol can work over two types of connection: in clear (called POP, default port 110) or over TLS (called POPs, default port 995). Hence, many different types of deployments could be performed:

TCP forward on POP (TCP/110) only

TCP forward on POPs (TCP/995) only

SSL offload on POPs (TCP/995) only

TCP forward on both POP (TCP/110) and POPs (TCP/995)

TCP forward on POP (TCP/110) and SSL offload on POPs (TCP/995)

Note

SSL offload means that HAProxy terminates the SSL/TLS connection and deciphers the traffic. It is not compatible with STARTTLS where the connection starts as clear and then switches to TLS. To be compatible with STARTTLS, use the TCP forward configuration.
